Samsung Multifunction Printer Error Code #02-001

The #02-001 error on a Samsung multifunction printer signals a fuser low heat fault. It means the fuser assembly failed to reach its required warm-up temperature, could not reach warm-up temp at all, or dropped below its target operating temperature for more than 10 seconds during ready or print mode. The printer stops all activity until the issue is resolved to prevent damage and maintain print quality.

A simple power cycle or reset will not permanently clear error #02-001 if a hardware fault is present. The error is triggered by the printer's thermal monitoring system and will reappear as soon as the printer attempts to warm up and detects the same low temperature condition. The underlying component causing the fault must be repaired or replaced before the error will stay cleared.

Repair costs vary depending on which component has failed. Replacement thermostats and thermistors are generally low-cost parts, typically in the range of a few dollars to around $20-$40 for the parts alone. A complete fuser assembly replacement, if the entire unit is damaged, can range from $50 to $200 or more depending on the printer model. Adding professional labor costs for diagnosis and installation will increase the total.

Start by checking the fuser thermostat, as this is the primary diagnostic step for this error. If the thermostat tests as defective, replace it. If the thermostat checks out, inspect the fuser heating lamp, thermistor, and all wiring connections to the fuser assembly. If those components are intact, testing the power supply board for proper output voltage to the fuser is the next step.

You should not continue using the printer with this error active. The fuser operates at high temperatures, and a malfunctioning fuser thermostat or heating lamp can create unpredictable thermal conditions. The printer's safety system has disabled operation for this reason, and bypassing the error without addressing the root cause is not recommended.
